The Magus [DVD]

This unusual fantasy stars Michael Caine as Nicholas, a teacher who arrives on a Greek island to begin a teaching position. He soon makes the acquaintance of the mysterious Conchis (Anthony Quinn), and his wife, Lily (Candice Bergen). Nicholas becomes fascinated with them, but something is amiss: the previous teacher who held Nicholas's job committed suicide under vague circumstances, and Nicholas himself is now exhibiting strange behavior. When his girlfriend (Anna Karina) comes to visit, tragedy strikes, and when Nicholas confronts Conchis he makes a surprising discovery.
